Testing Audi’s Traffic Light Information Tech On Real Roads

AudiFor many people, getting stuck at a red light is a lot like getting sucked toward a black hole. Time seems to slow down, either because the person behind the wheel thinks the light is taking too long to change, or because they think they now have an endless amount of time to send a text, sip a beverage, or generally ignore what’s going on in front of them.Audi is using technology to give drivers a bit more clarity. The German automaker’s traffic light information (or TLI, for short) system allows cars to “talk” to traffic lights, giving the driver a countdown to a green light. It’s a relatively simple feature that Audi said was designed to reduce driver stress, but the technology behind it could change the automotive landscape.But does this tech work today, in the real world? To find out, we grabbed the key fob of a 2019 Audi A8 and spent a few days motoring around one of the handful of United States cities where TLI is up and running. Red lights are usually the bane of drivers, but we sought out as many as we could find to give the system a full evaluation.How does it work?The system is a form of vehicle-to-infrastructure (V2I) communication. As the name suggests, this consists of adding equipment to vehicles and related infrastructure that allows them to transmit and receive messages. Anything equipped for V2I can send and receive data such as the location of a moving vehicle or, in the case of Audi’s system, the status of traffic lights.AudiSimilar systems exist to allow vehicles to communicate directly with each other. This is known as vehicle-to-vehicle communication, or V2V. Both V2V and V2I are sometimes collectively referred to as V2X (vehicle-to-everything). The basic concept is the same in all cases.This type of technology has been discussed for years as a way to improve safety and offer new services to drivers. Panasonic is testing out how the tech can improve safety at intersections in Denver, while Ford believes car-to-car communication could eventually eliminate the need for traffic lights and stop signs.In addition to being in the right geographic area, we needed the right car, and the right conditions, to get the benefit of TLI.Implementation has been fairly slow, however. Some automakers, like Cadillac and Mercedes-Benz, have preemptively equipped cars for V2X, without any real plan as to how to use the technology. Audi is the only automaker to use V2V/V2I/V2X to build new features for its customers. In addition to TLI, Audi offers an integrated toll transponder on certain models based on the same tech.V2I is the pipeline but, as is often the case with new tech, data is the oil. Audi partners with a third-party vendor called Traffic Technology Services (TTS) to get the data to predict when traffic lights will change. TTS works with municipalities to gain access to the data from traffic-control systems. It then uses that data and machine learning processes to predict upcoming traffic lights.AudiCities still have to grant access to their traffic-light data, though. TTS takes the lead on this, although it sometimes uses Audi and other customers to “lobby for strategic locations,” a TTS spokesperson told Digital Trends. TLI launched in 2016, and Audi claims it now works at more than 4,700 U.S. intersections in 13 municipalities including Los Angeles, Las Vegas, and Washington, D.C. Audi also recently added a feature – called green light optimized speed advisory (GLOSA) – that tells drivers the precise speed to catch the next green light. Audi is still a long way from full nationwide coverage, though.Read the fine printIn addition to being in the right geographic area, we needed the right car, and the right conditions, to get the benefit of TLI. The system is available on all 2019 Audi models except the A3, TT, and R8, as well as certain vehicles from model years 2018 (A4, A5, Q5/SQ5, and Q7) and 2017 (A4 and Q7).TLI requires an Audi Connect Prime telematics subscription. A six-month trial is included with new cars, but after that Audi charges $199 for six months, or $499 for 18 months. Granted, that rate also buys features like real-time traffic and fuel price information, Google Earth connectivity, and Google voice search.Audi wants drivers to pay attention to their surroundings when it’s time to move, not to a timer on their dashboards.The owner’s manual of our 2019 Audi A8 test car also noted that TLI is “subject to certain system...
